关于容器:安装KubeOperator并导入现有集群进行管理

装置 KubeOperator 并导入现有集群进行治理

介绍

KubeOperator 是一个开源的轻量级 Kubernetes 发行版，专一于帮忙企业布局、部署和经营生产级别的 Kubernetes 集群。

KubeOperator 提供可视化的 Web UI，反对离线环境，反对物理机、VMware、OpenStack 和 FusionCompute 等 IaaS 平台，反对 x86 和 ARM64 架构，反对 GPU，内置利用商店，已通过 CNCF 的 Kubernetes 软件一致性认证。

KubeOperator 应用 Terraform 在 IaaS 平台上主动创立主机（用户也能够自行筹备主机，比方物理机或者虚机），通过 Ansible 实现自动化部署和变更操作，反对 Kubernetes 集群 从 Day 0 布局，到 Day 1 部署，到 Day 2 经营的全生命周期治理。

# 获取 Api Server
[root@k8s-master01 ~]# cat ~/.kube/config | grep server: | awk '{print $2}'
https://192.168.1.69:8443

# 获取 Router
# 若应用 kubeadm 装置能够应用如下命令进行查看，若二进制装置应用节点 IP 即可
[root@k8s-master01 ~]# kubectl -n kube-system get pod -o wide | grep kube-proxy
[root@k8s-master01 ~]# 

# 获取 Token
